I just bought a 2005 Baja and would like to upgrade the engine to a WRX. Is this possible?

So I'm assuming your Baja is naturally aspirated?

WRX engine,

 

Turbo crossmember

 

WRX wiring loom to run engine.

 

That's probably the very basic requirements.  The wiring will be the big issue.

Possible? Anything is possible....

 

Practical? No.

 

This has been discussed tens, if not hundreds, of times (not necessarily on a baja...but there's nothing specific about that) It's not just an engine replacement. A turbo car has a lot of things that are different. You'll have $2k-10k into parts for the swap (There are a lot of variables on exactly what engine you use and where you get the parts. The WRX has been made since 1993, so a "wrx swap" is a very vague term). Not to mention the labor, the dash has to be gutted, you'll either have a wiring harness merge, or immobilizer stuff to deal with......

 

 

 

Subaru did this from the factory. You absolutely could sell your N/A Baja, and buy a Baja XT for less than it would cost to swap your Baja.
